52mm 7-in-1 Car Gauge Set with Tachometer, Boost, Vacuum, Water Temp, Oil Temp, Oil Press, Exhaust Temp, Voltmeter, AFR, and Red/Blue LCD Display

Get a complete picture of your engine's performance with this 52mm 7-in-1 car gauge set. It includes a tachometer, boost gauge, vacuum gauge, water temperature gauge, oil temperature gauge, oil pressure gauge, exhaust temperature gauge, voltmeter, and air-fuel ratio gauge. The red and blue backlight can be switched to match your car's interior lighting.

This advanced automobile instrument uses both digital and graphic displays to show real-time data. It is designed for 12-volt gasoline vehicles and helps you monitor critical engine functions. The set comes with sensors for boost, vacuum, water temp, oil temp, oil press, and exhaust temp. The air-fuel ratio gauge requires a separate narrow band oxygen sensor.

Installation is straightforward with the included English instructions. The sensor thread size is 1/8ZG. Two light lines let you switch between red and blue backlighting for a custom look. This gauge set is a practical upgrade for any car enthusiast who wants to keep a close eye on engine health.

Usage Scenario

Mark had just finished tuning his turbocharged 4-cylinder coupe. He wanted to make sure the engine was running safely under boost. He installed this 52mm gauge set in his center console. On his first test drive, he saw the water temperature climb during a hard pull. The oil pressure stayed steady, and the boost gauge showed he was right at his target. He was able to dial in his fuel mixture with the AFR gauge. Now he drives with confidence, knowing he can spot any problem before it becomes serious.

Micro Comparison

Unlike single-function gauges that require multiple separate units, this 7-in-1 set gives you all the essential readings in one package. It includes sensors for most functions, so you do not have to buy them separately. The switchable red and blue backlight is a feature not found on many basic gauges, making it easier to match your car's existing lighting.
